Description
Technical field
The invention belongs to the leathercraft protective sleeve and manufacture field, relate in particular to the mould in a kind of protective sleeve production, specifically the vexed mould of a kind of leather.The invention still further relates to a kind of leather stamping technique that utilizes the vexed mould of above-mentioned leather to realize.
Background technology
Under the leather protective sleeve, the product industry is an industry that coverage is very wide, the mobile phone external member of making such as leather, panel computer external member etc.Existing leather product generally be take the ox leather as raw material, and this raw material is that cattle hide is formed through the vegetable tanning agent tanning, is the raw material that a kind of stability is stronger.And the process of making protective sleeve is that the dimension of object that leather is protected according to packaging carries out cutting, then all parts is sewn into together and gets final product.Yet because present this protection suite major part is to be made and formed by several component combinations such as rear panel, anter, side wall, rear belt loops; anter, rear panel, side wall, rear belt loop need to be stitched together during stitching and form square-folded profile; finished product profile after order is sewed up is single, has following shortcoming:
(1) position that product need to be sewed up is many, causes the outward appearance of finished product not attractive in appearance, and indirectly increases cost, extends the time that unit product is produced;
(2) combiner is made inconvenience more;
(3) profile is single, and all parts are all by simply being stitched together, and the suture place, without transition, is all the structures at straightedge right angle, without aesthetic feeling, can say, and suture very easily weares and teares, and further impact is attractive in appearance.
Summary of the invention
In order to solve the above problems, the invention provides the vexed mould of a kind of leather, the leather sheath that order processes is when making whole parts, and still less, outward appearance is more attractive in appearance for suture, can enhance productivity simultaneously;
Another object of the present invention is to provide the leather stamping technique that the vexed mould of a kind of above-mentioned leather is realized.
For achieving the above object, the technical solution adopted in the present invention is as follows:
The vexed mould of a kind of leather, it comprises:
Upper bed-plate and lower bottom base; described upper bed-plate be provided with for the protection of the identical formpiston of contoured article; lower bottom base is provided with the former be complementary with formpiston, the thickness that is spaced apart institute's processing leather when described upper bed-plate contacts with the lower bottom base extruding between formpiston and former.
As limitation of the invention: it also comprises for the position and lock mechanism by formpiston and former alignement, described lockout mechanism comprises the contraposition nail of being located on upper bed-plate, and be located on lower bottom base, by with contraposition nail grafting contraposition after make former and formpiston be complementary registration holes.
As another kind of the present invention is limited: be respectively equipped with on described upper bed-plate and lower bottom base two bases are fixed in to the mace groove on lower platform on pressing machine.
As another kind more of the present invention is limited: described former limit mouth is provided with the groove that the witness marker line is provided for following process.
A kind of leather stamping technique, utilize the vexed mould of aforesaid leather to realize, this technique comprises the following steps:
(1) leather is placed: will need the grain side of leather of pressing mold to be placed in former down;
(2) pressing mold: utilize machine that formpiston is depressed towards former, and then the leather placed is carried out to pressing mold, and record the pressing mold time;
(3) pressing mold completes: after pressing mold completes, open former and formpiston, take out the leather that pressing mold is good stand-by.
As the restriction to above-mentioned stamping technique:
Being provided with before step (A1) mould in step (1) installs: upper bed-plate and lower bottom base are fixed on respectively on the upper mounting plate and lower platform of pressing machine as requested.
As the further restriction to above-mentioned technique: be provided with step (A2) pressing mold condition and set between described step (A1) and step (1): the pressure of setting pressure machine, time, temperature condition, specifically be set as: when the leather water content is not more than 15%, the pressing mold time is 30-50 seconds, mould temperature is 45 ℃-55 ℃, and pressing mold pressure is 0.3-0.4MPa.
Owing to having adopted above technical scheme, the present invention can reach following technique effect:
(1) the present invention can be compression molded into the leather product shape of mould by formpiston and the former arranged, the leather product of institute's pressing mold can form arc transition at the edge suture according to mould, before realizing, split and side wall skin unite two into one, form the die cavity of required protection object profile, closely realize reducing suture site, more smoother with the protective sleeve after sewing up season, prevent suture straightedge right angle and wear and tear;
(2) the present invention is provided with position and lock mechanism, makes formpiston and former accurately locate pressing mold, guarantees the effect of pressing mold;
(3) be respectively equipped with the mace groove on formpiston and former, can match with the mace of pressing machine upper mounting plate, the mace on lower platform respectively, make the easier for installation of formpiston and former.
In sum, the present invention is simple in structure, and more attractive in appearance in the time of can making the leather product sew up, the protective sleeve that order is made more lengthens work-ing life.
The present invention is applicable to make the protective sleeve of various article.
